Note the use of potassium sulphate

HAZARDS
Health hazard: inhalation, ingestion or skin absorption of harmful, with a stimulating effect. The long-term inhalation product dust can cause chronic manganese poisoning, to early neurasthenic syndrome and neurological disorder, and the late emergence of Parkinson’s syndrome. Environmental hazards: a hazard to the environment, can cause pollution of water bodies. Explosion hazard: This product is flammable, irritating.
first-aid
Skin contact: Remove contaminated clothing, mobile water rinse.
Eye contact: immediately filed eyelid, with large flows of water or saline thoroughly washed at least 15 minutes. Medical treatment.
Inhalation: rapidly from the scene to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, artificial respiration immediately. Medical treatment.
Ingestion: water were found to blues or egg white. Medical treatment.
Fire-fighting measures
Hazardous characteristics: not burning itself. Decomposition by high fever and emit toxic gases. Hazardous combustion products: sulfur oxides. Fire fighting methods: firefighters must wear fire protective body suits, the wind on fire. Try to move containers from the scene empty Department at the fire. Then select the appropriate fire extinguishing agent fire causes.
ACCIDENTAL
Emergency treatment: isolation leakage polluted area, restricting access. Recommended emergency personnel wearing dust masks, wearing overalls general operations. Do not direct contact with leakage. A small leak: to avoid dust, carefully scan, collect and transport the waste disposal sites. Large Leak: recycling or collection shipped to the waste disposal sites.
HANDLING AND STORAGE
Handling Precautions: closed operation, local exhaust ventilation. Prevent dust released into the air workshop. The operator must go through specialized training, strict adherence to rules. Proposed operators wear self-absorption filter respirators, wearing chemical protective safety glasses, wear protective overalls on infiltration, wear rubber gloves. Avoid generating dust. Avoid contact with acids. Equipped with spill response equipment. Empty containers may be harmful residues. Storage: Store in a cool, ventilated warehouse. Away from fire, heat source. Prevent direct sunlight. Sealed packaging. Keep away from acids, avoid mixing reservoir. Storage areas should be equipped with suitable material spill.
preparation
With sulfate of potash and potassium salt lake brine as the raw material from the system. Can also be used 98% sulfuric acid and potassium chloride reacted at an elevated temperature, concentrated by evaporation, cooling and crystallization, centrifugal separation, drying, hydrogen chloride generated during the reaction, the absorption of water by-product hydrochloric acid. With alunite reduction pyrolysis legal system. Sulfuric acid and potassium chloride from the reaction system. Mixing sulfuric acid and potassium sulfate may be obtained: H2SO4 + KOH = K2SO4 + H2O
